Abstract

1309920 Gear-change mechanism FICHTEL & SACHS AG 18 Dec 1970 [24 Dec 1969] 60127/70 Heading B7E A cycle gear-change mechanism comprises a frame 1 on which is mounted a change lever 2, the frame being mounted on a base-plate 17 from which extends a pair of straps 22 for attachment of the mechanism to a handle bar 6, one strap on either side of steering head 7, there being connected to the lever 2 a linkage or a push-pull cable 4 which connects with the gearing, and there being also provided on the lever spindle a leaf spring which presses balls into detents 5 in the frame by means of which the lever is held in the gear positions. A housing 11 is connected to the frame by a screw 10 and projection 8. A bracket 14 of the frame mounts a bell 12 which extends from the rear of the housing, and clipped to the front of the housing is a head tight 19. A speedometer 15 may be embedded in an aperture 18 of the housing. In a modification, the straps 22 are replaced by a shackle which is attachable to the connecting piece 30 between the steering head 7 and handle bar 6 by a bolt 23 which also serves to clamp the connecting piece to the handle bar.
